摘要
依据渗流力学理论和油藏工程理论,综合分析油井生产历史数据,利用多元回归方法,建立压前自然递减生产动态的模拟模型;利用不稳定试井理论,建立压后含有水平裂缝生产井的产量递减模型;综合压前压后产量递减模型,确定了压裂有效期的计算方法。
Based on permeation fluid mechanics and reservoir engineering theory,historical production data of oil wells were synthetically analyzed,dynamic simulation model of natural production before fracturing was established by multiple regression method.Decline model of oil production for the fractured well with horizontal fractures was established by unstable well testing.The calculation method of fracturing validity was finally determined by adopting above two models.
